ain, residing at Halifax, in the county of. York, England, have invented nevi and useful Improvements in and Relating to Oil- Engines,'of which the following is a specification. i

This invention relates more especially to small power engines using heavy oils, Where tinuously in order to keep the vaporizer and ignition tube hot enough to insure a constant or positive ignition.

The object of my invention is to set up an automatic or positive ignition in Vaporizers forming part of the combustion chamber; by placing said vaporizer-"and an ignition tube immediately in the-path of the hot gases from the exhaust, and to heat the same by the said gases in their'passage to the exhaust outlet pipe. Inthis manner I am enabled to dispense With the ordinary lamp and ignition after the enginehas got fairly start ed, and soefi'ect a great" saving in oil, or the expense of an electric ignition. In connection' with m invention 1 fix the'vaporizer side elevation of Fig. 1; v Similar letters refer to similar parts and i nition tube at the exhaust end ofthe cylinder, and surroundthe said" vaporizer with a suitable jacket having an inle't and Theiinlet isconnected by pipe" with the exhaust, and the outlett'o a further I pipe connectioafor conveying the exhaust an outlet.

I attain these objects by the-means illustrated in the accol'npanyingdrawings, in Which'- 7 Figure l is-a sectional side elevation of vaporizer secured to an oil engine cylinder;

The vaporizer Ajrvvhich is also part of the en the engine commences running, the

hot gases from the exhaust iinmediatelvim pinge against the tube K and sides of the vaporizerA in their passage to the outlet pipe J, so that once the engine is fairly started in the ordinary Way, the hot gases in their passage along the exhaust pipe uni formly heat the ignition tube and vaporizer in such a manner as to set up a positive ignition under varying loads or all conditions of running.
